How to send a File to Server in android programming

This is an easy Android application which allows to send a file in any format to a remote server. Server acts as loacalhost and create a button in a linear layout and the oprationvwill taking places in the android app is on button press. It will allows to send a file to server.There are mainly 4  portions for this operations. First one is an input device, which is an android device who send file to the server :- easyClientActivity.java.

easyClientActivity.java has the code for sending file. next one is main.xml, which creates the layout and user interface for the application. 3rd one is AndroidManifest.xml , it has the codes for some permission for using the network operations. main.java is the 4th module which comprises the code for server portion, allows to recieve the file.

easyClientActivity.java

  package lakj.comspace.easyclient; import java.io.BufferedInputStream; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.OutputStream; import java.net.Socket; import java.net.UnknownHostException; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.TextView; public class SimpleClientActivity extends Activity { private Socket socketforclient; private FileInputStream inputStreamForFile; private BufferedInputStream streamForBufferedInput; private OutputStream stremForOutput; private Button SendButton; private TextView TextviewFortext; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); SendButton = (Button) findViewById(R.id.SendButton1); //reference to the send SendButton TextviewFortext = (TextView) findViewById(R.id.TextviewFortextView1); //reference to the TextviewFortext view //Button press event listener SendButton.setOnClickListener(new View.OnClickListener() { public void onClick(View Viewv) { File file = new File("/mnt/sdcard/input.fileextension"); try { socketforclient = new Socket("10.0.2.2", 4444); byte[] ByteArrayForMe = new byte[(int) file.length()]; //create a byte array to file inputStreamForFile = new FileInputStream(file); streamForBufferedInput = new BufferedInputStream(inputStreamForFile); streamForBufferedInput.read(ByteArrayForMe, 0, ByteArrayForMe.length); //read the file stremForOutput = socketforclient.getOutputStream(); stremForOutput.write(ByteArrayForMe, 0, ByteArrayForMe.length); //write file to the output stream byte by byte stremForOutput.flush(); streamForBufferedInput.close(); stremForOutput.close(); socketforclient.close(); TextviewFortext.setText("File Sent"); } catch (UnknownHostException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } }); } }  

Main.Xml

  <linearlayout android:layout_height="fill_parent" android:layout_width="fill_parent" android:orientation="vertical" xmlns:android="http://schemas.android.com/apk/res/android"> <textview android:id="@+id/textView1" android:layout_height="wrap_content" android:layout_width="wrap_content" android:textappearance="?android:attr/textAppearanceLarge"> <button android:id="@+id/button1" android:layout_gravity="center" android:layout_height="wrap_content" android:layout_width="wrap_content" android:text="Send"> </button></textview></linearlayout>  

AndroidManifest.xml

  <manifest android:versioncode="1" android:versionname="1.0" package="lakj.comspace.simpleclient" xmlns:android="http://schemas.android.com/apk/res/android"> <uses-sdk android:minsdkversion="10"> <uses-permission android:name="android.permission.INTERNET"></uses-permission> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name"> <activity android:label="@string/app_name" android:name=".SimpleClientActivity"> <intent-filter> <action android:name="android.intent.action.MAIN"> <category android:name="android.intent.category.LAUNCHER"> </category></action></intent-filter> </activity> </application> </uses-sdk></manifest>  

main.java

  package serverwithdata; import java.io.BufferedOutputStream; import java.io.fileoutputdatastream; import java.io.IOException; import java.io.fileinputdatastream; import java.net.ServerSocket; import java.net.Socket; public class Main { private static ServerSocket serverSocket; private static Socket clientSocket; private static fileinputdatastream fileinputdatastream; private static fileoutputdatastream fileoutputdatastream; private static BufferedOutputStream bufferedOutputStream; private static int filesize = 10000000; private static int bytesReadData; private static int LiveData = 0; public static void main(String[] args) throws IOException { serverSocket = new ServerSocket(4444); //Server socket System.out.println("Server started. Listening to the port 4444"); clientSocket = serverSocket.accept(); byte[] BytesArrayforData = new byte[filesize]; fileinputdatastream = clientSocket.getfileinputdatastream(); fileoutputdatastream = new fileoutputdatastream("D:\\output.jpg"); bufferedOutputStream = new BufferedOutputStream(fileoutputdatastream); System.out.println("Server ready for accept file and working for this"); bytesReadData = fileinputdatastream.read(BytesArrayforData, 0, BytesArrayforData.length); LiveData = bytesReadData; do { bytesReadData = fileinputdatastream.read(BytesArrayforData, LiveData, (BytesArrayforData.length - LiveData)); if (bytesReadData >= 0) { LiveData += bytesReadData; } } while (bytesReadData > -1); bufferedOutputStream.write(BytesArrayforData, 0, LiveData); bufferedOutputStream.flush(); bufferedOutputStream.close(); fileinputdatastream.close(); clientSocket.close(); serverSocket.close(); System.out.println("Server has got the file you send from clent device"); } }

How to program backgound image wallpaper android development

Here we are going to explain about, how set and fix an image as wallpaper and changing its properties in an android application.It is simple to set an image as a wallpaper, there are different small problems that need to be addressed to sharply fix a wallpaper.This app will enables you to generate a wallpaper for each day which replaces automatically every morning, this tip helps to a number of points which will help in setting the wallpaper.

Create activity to Get an image from your Album: Android image operations are taking places by a class called Intent. Intent is an abstract description of an opration that will happend.Intent allows to peform possible opration mean while in the code.

Intent objintent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI); startActivityForResult(objintent, RESULT_LOAD_IMAGE);

Set your picture from Album: it is setting the image that you have selected for further process.

@Override protected void onActivityResult(int CodeForRequest, int CodeForResult, Intent objContent) { super.onActivityResult(CodeForRequest, CodeForResult, objContent); try { if (CodeForRequest == RESULT_LOAD_IMAGE && CodeForResult == RESULT_OK && null != objContent) { Uri YourImageBySelection = objContent.getData(); String[] SelectedImagePath = { MediaStore.Images.Media.DATA }; Cursor cursor = getContentResolver().query( YourImageBySelection,SelectedImagePath, null, null, null); cursor.moveToFirst(); int NumberOfColumn = cursor.getColumnIndex(SelectedImagePath[0]); String picturePath = cursor.getString(NumberOfColumn); cursor.close(); ImageButton btnImage = (ImageButton) findViewById(ButtonIdToSet); File newFile = new File(picturePath); if(newFile.exists()) { Bitmap bmpBitmap = decodeFile(newFile, btnImage.getWidth(),btnImage.getHeight()); btnImage.setImageBitmap(bmpBitmap); } } } catch (Exception Ex) { Ex.printStackTrace(); } }

Android Bitmap properties Setting:-

Setting hight and width properties fo your bitmap for wallpaper:Creating a new file and set hight and width of that file for pic. enabling the bitmapfactory options.This will result an images size ratio at last.

public static Bitmap decodeFile(File NewFile, int WidthBitmap, int HightBitmap){ final BitmapFactory.Options properties = new BitmapFactory.Options(); properties.inJustDecodeBounds = true; BitmapFactory.decodeFile(NewFile.getPath(), properties); properties.ArrangedSize = ArrangedInSizeByme(properties, WidthBitmap, HightBitmap); properties.inJustDecodeBounds = false; return BitmapFactory.decodeFile(NewFile.getPath(), properties); } private static int ArrangedInSizeByme( BitmapFactory.Options properties, int WidthBitmap, int HightBitmap) { final int iHight = properties.outHeight; final int iWidth = properties.outWidth; int ArrangedSize = 1; if (iHight > HightBitmap || iWidth > WidthBitmap) { final int hightManaged = Math.round((float) iHight / (float) HightBitmap); final int widthManaged = Math.round((float) iWidth / (float) WidthBitmap); ArrangedSize = hightManaged < widthManaged ? hightManaged : widthManaged; } return ArrangedSize; }

Before setting the picture that you have selected as wallpaper, you need to maintanin and manage the display prperties of your android device. And then set the image as wallpaper of your device.
//Managed Display parameters for setting image DisplayMetrics DMetricsDisplay = appContext.getResources().getDisplayMetrics(); int iHight = DMetricsDisplay.heightPixels; int iWidth = DMetricsDisplay.widthPixels; //Bitmap Setting Bitmap NewBitmapSetting = decodeFile(NewFile,iWidth,iHight); myWallpaperManager.suggestDesiredDimensions(iWidth, iHight); myWallpaperManager.setBitmap(NewBitmapSetting);
